Wireless Disconnecting - Windows 7 64-bit mostly

Several Windows 7 64-bit systems (laptop computers mainly) seem to loose their wireless network connection at varying and not specified times under varying circumstances.

Searching in Google and in Microsoft's support forum I found three different methods documented that seem to have done the trick for various people. I post these methods here in an attempt to give at least some help.

Method 1: Disable IEEE 802.1X authentication
To disable IEEE 802.1X authentication, follow these steps:

• Click Start, type ncpa.cpl, and then hit Enter.
• Right-click your wireless network connection and click Properties.
• Click the Wireless Networks tab.
• In Preferred networks, click your wireless network and click Properties.
• Click the Authentication tab, click to clear the Enable IEEE 802.1X authentication for this network check box, and then click OK two times.

Method 2: Remove and re-create the wireless network connection
To remove and re-create the wireless network connection, follow these steps:

• Click Start, type ncpa.cpl, and then hit Enter. 
• Right-click your wireless network connection and click Properties.
• Click the Wireless Networks tab.
• Under Preferred networks, click your wireless network and click Remove.
• Click View Wireless Networks.
• Under Network Tasks, click Refresh Network List.
• Under Choose a wireless network, click the wireless network to which you want to connect and click Connect.
  

Method 3 requires to work within your router.
If you are not used to do that - frankly, you better call me.

But for those of you that are not faint of heart: Here it is, written for a D-Link 655 router. If you have a different router the same things may be called VERY differently; be cautious!

• Un-check WMM (Wireless Multi Media)
• Un-check Short GI (Guard Interval) and
• Un-check Extra Wireless Protection.

Warning: These are methods that have helped other people with this problem to varying degrees. If you have a D-Link router I might actually try method #3 first.

Either way you apply any of these methods exclusively at your own risk. I did not have this problem and thus can not test any of the above.

As usual I welcome comments and suggestions right here in the blog. Thank you in advance.
